An apparatus of a base station in a wireless communication system supporting time division duplex (TDD) and a method thereof are provided. The apparatus includes at least one transceiver, and at least one processor operatively connected with the at least one transceiver. The at least one processor may be configured to perform signaling for preventing transmission of an uplink (UL) signal in a cell, and measure a strength of a downlink (DL) signal received from at least one base station during at least one symbol in a UL subframe. The apparatus relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long-Term Evolution (LTE).

Apparatus and method for managing interference in wireless communication system

An apparatus of a base station in a wireless communication system supporting time division duplex (TDD) and a method thereof are provided. The apparatus includes at least one transceiver, and at least one processor operatively connected with the at least one transceiver. The at least one processor may be configured to perform signaling for preventing transmission of an uplink (UL) signal in a cell, and measure a strength of a downlink (DL) signal received from at least one base station during at least one symbol in a UL subframe. The apparatus relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long-Term Evolution (LTE).

A method for operating an apparatus that performs traffic control traffic in a wireless communication system is provided. The method includes receiving information about a terminal to be controlled, detecting a congestion situation in a cell, and changing a parameter relating to scheduling of the terminal to be controlled, according to the detection of the congestion situation.

Apparatus and method for controlling traffic in wireless communication system

Provided is a method for balancing load of a server in a communication system. The method includes receiving, by a client, a new access request message; checking load status of servers that the client itself manages; selecting a lowest-load server among the servers as a server to which the client is to send the new access request message; and sending the new access request message to the selected server.

Method and apparatus for load balancing in communication system

An apparatus and method for dynamically allocating a multicast path in a broadband wireless access system are provided. A method for an operation of a server providing a multicast service through a wireless access network includes determining to establish multicast paths for a first Base Station (BS) and at least one neighboring BS of the first BS when a terminal receiving the multicast service enters a network through the first BS, and transmitting a control station a message of instructing to establish the multicast path for a BS not holding the multicast path among the first BS and the at least one neighboring BS of the first BS.

Apparatus and method for dynamically allocating multicast path in broadband wireless access system

An apparatus and a method for managing an access state of a terminal for a group communication service in a wireless communication system are provided. In a method for operating a terminal for a group communication service in a wireless communication system, a bandwidth ranging message is transmitted to a base station in an idle state. The terminal is allocated an uplink resource from the base station. A message for access state transfer including a multicast Connection IDentifier (CID) is generated. The message for access state transfer is transmitted to the base station via the allocated uplink resource.

Apparatus and method for managing access state of mobile station for group communication service in wireless communication system

An apparatus and a method for setting a group communication session using a wireless access system are provided. The method includes transmitting, at a transmission side client, a message requesting start/end of group communication to a control Push To Talk (PTT) server, transmitting, at the control PTT server, a session set/end message including a sequence number to a participating PTT server, multicasting, at the participating PTT server, a connect/disconnect request message N times for at least one reception side client, and setting/releasing, at the at least one reception side client, a session for the group communication.
